MACHINE FOR DRYING AND FLUXING METAL SHEETS.

SPECIFICATION forming part of Letters Patent No. 722,643, dated March10, 1903.

Application filed November 24, 1900. Serial No. 37,600. (No model.)

To all whom it may concern:

Be it known that I, JOHN C. TALIAFERRO, a citizen of the United States,residing in Baltimore, in the State of Maryland, have invented a new anduseful Improvement in Machines for Drying and Fluxing Iron, Steel, orother Metal Sheets Preparatory to Tinning the Same, of which thefollowing is a specification.

My invention relates to fluxing-machines used in the manufacture oftin-plate.

It consists in the novel construction of parts and devices and in thenovel combinations of parts and devices herein shown and described, andspecified in the claims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a side elevation of a machine embodying my invention. Fig. 2is a plan view, and Fig. 3 is a central vertical longitudinal section.

In the drawings, A represents the frame of the machine.

B B are the drying and fluxing rolls, the same being hollow andsteam-heated through the steam-pipes O O by which steam is admitted tothe interior of the rolls.

D is the feed-table, the same having a series of converging rails 61 (1upon which the sheets are placed and which operates as the sheets arepushed forward over the same to partially scrape the water from theirsurface, owing to the fact that the rails converge or extend at an angleto the direction of movement along the feed-table. The feed-table isfurther provided with side guides or gages d (1 one of which, d isadjusted to and from its fellow d by means of the brackets d furnishedwith a series of notches or holes 01 in which fit pins 61 by which thisadjustable gage is secured in place. These converging rails d on thefeed-table serve to partially free the sheets from the water adhering totheir surface as they are taken out of the water bath or vessel E andplaced upon the feedtable.

The metal sheets are fed forward into the bite of the first pair ofrolls B by means of a vibrating feeder, preferably consisting of aseries of fingers F, secured to a rock-shaft F,

which is rocked at intervals, as required, by

tact with the water.

means of cam f, through the lever f and link f which connectswith thearm f on the rock-shaft.

G is the flux bath or vessel, the same being furnished with atrap-discharge g, the upper end or leg g of which extends above thebottom of the vessel sufficiently to prevent the palm-oil or flux fromflowing out,while at the same time it'terminates sufliciently below theupper edge of the vessel to permit the water which collects in thebottom of the flux vessel from the wet sheets passing through themachine to automatically discharge, the water of course bcin g heavierthan the oil and separatingtherefrom. The outer discharge end g of thetrap extends up to a less height than the level of immersion of therolls in the flux to keep the rolls from coming in con- The flux vesselG is supported by hooks g g from rods 9 on the frame of the machine. Thehooks g are spring-hooks to enable the vessel to be convenientlyunhooked at one end when it is desired to empty it. Beneath the fluxvessel G is a collecting vessel G for overflowing oil and water, thesame having an upper faucet and K is a curved connecting-chute fordespout-shaped flux vessel M, open at both ends and projecting at itslower end into the molten tin 7c in the tinning-pot K and extendingsufi'iciently beneath the surface of the molten tin to enable thecomparatively small amount of flux in the vessel M to stand atconsiderable height above the surface of the molten tin withoutspreading over its surface or causing the molten tin to overflow the potK or rise to too-great height therein, this action or operation beingdue to the great difference in specific gravity between the molten tinand the palm-oil or other flux. This secondary narrow or trough-shapedfiuxing vessel M thus combined with the tinning-pot operates, inconnection with the fiuxiug-rollers D D and their flux vessel G, toinsure the complete and perfect fiuxing of every portion of the entiresurface of each and every sheet passing through the machine, as well'asto completely expel from the surface of the sheet all water or moisture.This combination of parts also prevents all danger of and obviates alltrouble from the flux on the molten tin in the tinning-pot foamingorboiling over and catching fire, as has heretofore been experiencedwhere the flux on the molten tin is permitted to spread over the Wholesurface of the molten tin in the tinning-pot. The secondary open-endedfiuxing vessel M has an overflow spout or passage M near its upper endfor the surplus flux collecting therein from the fluxed sheets as theypass into the tinningpot. This overflow-discharge spout M projects overthe collecting vessel G, into which the surplus flux is discharged. Thesecondary or supplemental fluxing vessel M is also provided with curvedor inclined guide-bars N, which are hooked onto its upper edge and serveto direct the metal sheets centrally and properly into the tinning-potfrom the curved connecting spout or chute K.

P is the driving-shaft, having a drivingpulley P and suitable gearing pp communicating motion from it to the fiuxing-rollers D, and the cam f,which operates the feeder, receives its revolving movement from one ofthe fiuxing-rollers through the connectinggearing p p. The gearing p 19preferably comprises a pair of bevel-gears, connecting spur-gears,sprocket gears and chains, as indicated in the drawings, and the gearingpp' preferably consists of sprocket gears and chains.

I claim- 1. In a fluxing-machine, the combination with revolving,steam-heated fluxing-rollers, of a fluxing bath or vessel in which thelower fluxing-rolls revolve, a feed-table having converging rails forsupporting the sheets and a feeder for pushing the sheets on said rails,a counter mechanism, a counter-arm projecting in the path of thesheets,a tinning-pot, a secondary contracted or spout-shaped fiuxvessel, open at both ends and projecting at its lower end into the(inning-pot, a curved chute for delivering and directing the sheets fromthe fiuxing-rolls into said secondary fluxing vessel, a collectingvessel, an overflow discharge-spout leading from said secondary fiuxingvessel, and a trap dischargepipe leading from the bottom of the mainfluxing vessel and having its upper end or leg terminating below theupper edge of said main fiuxing vessel, substantially as specified.

2. The combination with a fluxing vessel, of fluxing-rolls, a feed-tablehaving rails for the sheets to rest upon extending at an angle to thedirection of the movement of the sheets on the feed-table, and a feederfor pushing the sheets along said rails, substantially as specified.

3. The combination with hollow fiuxingrolls, of means for heating saidrolls, a fluxing vessel containing oil or flux in which the lower rollsrevolve, and provided with a trap water-discharge for automaticallyseparating from the oil or flux in the fluxing vessel the water whichcollects from the wet sheets passing between the fluxing-rolls, theouter leg of the trap extending up to a less height than the level ofimmersion of the rolls in the flux to keep the water in the flux vesselout of contact with the rolls, substantially as specified.

4. The combination with hollow fluxingrolls, of means for heating saidrolls, a fluxing vessel containing oil or flux in which the lower rollsrevolve, and provided with a trap water-discharge for automaticallyseparating from the oil or flux in the fiuxing vessel the water whichcollects from the wet sheets passing between the fiuxing-rolls, and awatercollecting vessel below the fluxing vessel, the outer leg of thetrap extending up to a less height than the level of immersion of therolls in the flux to keep the water in the flux vessel out of contactwith the rolls, substantially as specified.

5. The combination of fiuxing-rolls with a fiuxing bath or vessel belowthe rolls, a feedtable and feeder, a tinning-pot and a curved chute forreceiving the sheets horizontally from the fiuxing-rollsand deliveringand defleeting them vertically into the tinning-pot, substantially asspecified.

6. The combination of fluxing-rolls with a fluxing bath or vessel inwhich the lower rolls revolve, a feed-table and feeder, a tinningpot, acurved chute for delivering and deflecting the sheets from thefluxing-rollers into the tinning pot, and a supplemental narrow,open-ended flux-containing vessel projecting at its lower end into themolten tin in the tinning-pot, substantially as specified.

7. The combination of fluxing-rolls with a fluxing bath or vessel inwhich the lower rolls revolve, a feed-table and feeder, a tinningpot, acurved chute for delivering and deflect= ing the sheets from thefiuxing-rollers into the tinning-pot, a supplemental narrow, openendedflux-containing vessel projecting at the lower end into the molten tinin the tinningpot, and an overflow discharge-spout at the lower end intothe molten tin in the tinning- IO pot, and guide-bars for the sheetsinsaid supplemental fluxing vessel, substantially as specified.
